How to send a signed message with Local Account

[thejasondt]

Hey!

I have recently moved over from Ethers to viem and am struggling to writeContract from Local Account with viem and Infura.

The ethers code is pretty simple with const signer = wallet.connect(provider) (const wallet = new Wallet(privateKey, provider)
that we pass to the new Contract before calling contract.enterFunction

There isn't an equivalent in the migration guide of creating a signer from the wallet as I do in Ethers.

When I try const hash = await walletClient.writeContract(sim) in viem I get:

"Server error TransactionExecutionError: The method does not exist / is not available.\n\nURL: wss://sepolia.infura.io/ws/v3/apiKey\nRequest body: {"method":"eth_sendTransaction","params":[{"data":"","from":"","to":""}]}\n \nRequest Arguments:\n from: \n to: \n data: \n\nDetails: The method eth_sendTransaction does not exist/is not available\nVersion: [email protected]"

Is Ethers using eth_sendRawTransaction under the hood as opposed to eth_sendTransaction

How can I send a signed message/send raw with writeContract or another way around this?

Do you have your Local Account attached to the walletClient? https://viem.sh/docs/clients/wallet.html#optional-hoist-the-account-1

Yep,

const account = privateKeyToAccount('0x' + privateKey) const walletClient = createWalletClient({ account, chain, transport });

Do I need to add the Local account to PublicClient also when doing the sim? EDIT: no, it does no accept account as a var

I am adding the { request } from simulateContract to writeContract

Can you pop a link to a minimal reproduction? Can use new.viem.sh as a starting point.

I found the issue.

I needed to simulateContract with the Local Account also - perhaps it would be good to hoist to publicClient as with the walletClient
